Abstract: A localization method for locating a target that is coupled with a locator transponder associated with a permanent identification code permanently assigned to the locator transponder is provided.

Abstract: The invention relates to an interconnection network for forward error correction encoders and decoders, including N input terminals, N output terminals, and M stages. Each stage includes switching elements having input pins and output pins. The input pins of the switching elements of the first stage are connected to the input terminals, and the output pins of the switching elements of the last stage are connected to the output terminals. The input and output pins of the switching elements of immediately successive stages are connected in a hardwired fashion so as to form a plurality of interconnection sub-networks for routing respective input values from respective output pins of the switching elements of the first stage to respective input pins of the switching elements of the last stage.

Abstract: The present invention concerns a localization method for locating a target that is coupled with a locator transponder associated with a permanent identification code permanently assigned to said locator transponder; the localization method comprising: upon reception of a user request for locating the target, transmitting, by a paging system or by a radar-based system, a spread spectrum paging signal carrying the permanent identification code and a temporary identification code temporarily assigned to the locator transponder, wherein said temporary identification code is shorter than said permanent identification code; receiving, by the locator transponder, the spread spectrum paging signal and extracting, by said locator transponder, the temporary identification code carried by said spread spectrum paging signal received; transmitting, by the radar-based system, radar signals towards one or more areas of earth's surface or sky, and receiving, by said radar-based system, echo signals from said one or more area

Abstract: A hybrid processor system for use on board a telecommunications multi-beam satellite is provided that is controllable by a network control center via one or more control channels. The system links to ground terminals by: providing uplink and downlink traffic channels on several satellite beams; routing atomic switched information blocks from the uplink traffic channels to the downlink traffic channels; and exchanging signaling data with the ground terminals on one or more uplink signaling channels and one or more downlink signaling channels. The atomic switched information blocks have the same given time duration and the same given baseband bandwidth.
